Patented Aug. 6, 1907.

new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to type actions and morepariticularly. to the type bars and hangers thereof.

One of the main objects of my invention is to provide simple and efiicient means whereby a large'number of type bars can be mounted in a comparatively small space, or on a short type bar segment, and have widely separated pivot bearings. 15'

' Another object is to reduce the number of separate hangers and to provide for their firm securement in position.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangement of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters represent corresponding parts in the different views, Figure 1 is a side view of two type actions embodying my invention; the frame of the machine and platen being shown in dotted lines; Fig. 2 is a detail front elevation of the type bar segment with some of the hangers shown in place; Fig 3 is a detail side elevation of two of the type bars and the hanger therefor secured to the segment, the segment being shown in section; Fig. 4 is an enlarged detail front elevation showing a type bar hanger secured to the segment with two type bars mounted therein and illustrated in the printing position, one bar being shown in dotted lines; Fig. 5 is an enlarged detail plan view of one of the hangers; Fig. 6 is a transverse sectional view of the same taken onthe'line a; a: of Fig. 5.

While I have shown my invention applied to a frontstrikemachine it should be understood that it may be embodied in various -other styles of typewriting machines. I 7

Key levels 1 are pivoted at 2 in the base of the frame of the machine, and each key lever is provided with the usual finger-key 3 and restoring spring 4. An inclined sub-lever 5 has a forwardly extending off-set portion 6 by which it is pivoted at 7 to its associated key lever. The lower end portion of each sub-lever is slotted at 8 for the reception of a fixed fulcrum bar 9 that extends from side to side of the machine beneath the keyleversand is secured to the frame of the machine. The upper end of each sub-lever is pivoted at i 10 to a rearwardly extending downwardly curved link 11, the opposite end of the link being pivoted at 12 to a crank projection 13 on the associated type bar so that each type bar swings ina median plane between 3 pair of arms.

Each type bar has laterally extending trunnion-like pivots 15 that are conoidal or tapering at the ends where they seat in counterpart bearings 15 in arms 16 of type bar hanger 17. The pivots project to equal extents on opposite sides of the type bars and the pivot of each bar extends at right angles to the hanger arms,

its bearings and wear upon both bearings of each bar'is evenly distributed. Each hanger is preferably formed of sheet metal with a substantially U-shaped stem or shank 18. I

A shouldered stud or rivet 19 is interposed between the sides of the substantially U-shaped shank of each hanger and the reduced ends of each stud pass through openings in the sides of the shank and are riveted or headed, in order to form a firm connection between the separated plate portions of the shank and thus prevent relative displacement between the side arms 16 of the hanger. The sides of each hanger are slitted at 20 so as to divide the hanger into two sets of type-bar bearing arms 16. Each cooperating set of arms 16 is off-set or staggered relatively to the other set of arms formed on or as a part of the same hanger. In other words, it will be seen on examination of Fig. 4 that the upper set of arms is bent laterally to the left and that the arms of said set are substantially parallel at their forward end port-ions, whereas the arms 16 of the lower set are bent bring about a movement of the type bar in the proper ,plane. In this manner the type bar which is pivoted g to a lower pair of arms maybe arranged radially of the printing point and likewise that pivoted to the upper While the two type bars are mounted in f the same hanger they may, nevertheless, each be provided with a long pivot 15 and one set of arms on the hanger may overlap the arms of the other set.

Each

5 set of arms 16 has a transverse headed screw 21 which T extends between the arms and one end of the screw enters a threaded opening in one of the arms, whereas 7 the head 21 of the screw is seated in a countersunk in in the other arm. By turning the screw 21 the associated arms of the hanger controlled by said screw may be brought closer together or maybe allowed to separate in order to effect a proper relative adjustment between the arms of each set, to properly assemble the 1 parts and to compensate for any wear between the pivots 15 and their bearings 15. e

I A type bar segment 22 has a series of spacing lugs 23 on the lower edge thereof, and near each spacing lug a plain hole 24 is drilled through the segment to receive a headed screw 25. Each screw projects through the ment at the rear side thereof.

with shoulders 27 which are adapted to bear against the underside of the segment uponopposite sides of its as- U-shaped stem of its associate dupleir hanger and cooperates with a nut 26 that straddles or overlaps both plates of the stem, thus securing the hanger to the segsociated spacing lug 23. The sides of the lugs being cut on the proper'radii, the proper radial position of each hanger on the segment is thus readily predetermined, and inasmuch as the lugs 23 fit snugly between the shouldered portions of the hangers, the latter are prevented from swinging laterally about their holding screws, and from twisting or otherwise getting out of true position. 'The hangers thus secured to the rear face of'the segment project around the bottom edge thereof ter, as the side bars have a greater tendency to get out of alinement than those at the center of the segment.

This tendency is due to the fact that the type bars swing in planes which approach the horizontal, and the gravity'of the bars causes them to wear their bearings more on the inner or lower side and to develop shake,

which at the type end is reduced to a minimum by the use of long pivots. The center bars swing in planes which approach the vertical, and their tendency to lateral deflection is less than that of the side bars, and hence their pivots maybe shorter.

Each of the type bars 14, that is pivoted in the lower set of hanger arms, is formed with a recess at 14 in order to enable it to clear the upper set of hanger arms and the pivot. of the other type bar mounted on the same hanger, as indicated in Fig. 3.

Referring more particularly to Figs. 1 and 2, it will beseen that the type bars mounted on each hanger are pivoted at different distances from the printing point; that all the upper pivots are alined in an are indicated by the dotted line A, whereas all the lower pivots are alined in an are indicated by the dotted line B; that the pivot of each type bar is parallel to the plane of the type bar segment; that the pivots of the type bars on each hanger are arranged in an inclined plane represented by the dotted line a, which is substantially midwaybetween the printing point and the type bearing ends of the type bars when at rest, and that this plane is at substantially right angles to a line indicated at b,

to provide ,the overlapping arrangement heretofore described at the bearings, with long pivots for each type bar, but when the type bars are at rest inthe basket bar hanger comprising a plurality of sets of hanger arms,

they are alined or-in one row at their forward tr typeends, notwithstanding the fact that the pivots of the type bars are arranged at different distances from the printing point and that the bars themselves are of different lengths. I I

Each curved link 11 which extends forwardly from Each hanger is provided by each hanger. drawn from the printing point to a type on one of the i type bars. By this arrangement I am enabled not only eraily relatively to the arms 01 another set, and means for affording a relative adjustment between the arms of each its type bar is pivotally connected thereto in the same plane (a) that the pivots of the associated type bars are located in.

' The typebar segment may be secured in place by any suitable means, as by headed screws 28 the stems of which pass freely through holes 28 in the segment and are received in threaded openings within a portion 29 a of a part of the machine that may beshifted in any suitable manner, in order to change the relation between the type bars and the platen. .I'f desired, however, the platen may be shifted relatively to the type bars.

From an inspection of Fig. 2, it will be seen that each -terminal type bar hanger has a bent or off-set arm 16 with the pivot bearing vportion thereof at a height coextensive with or extending above the screw-which S cures the hanger in place and an associated substantially straight hanger arm 16 radially disposed from the printing center and that these two arms support a terminal type bar in place. The purpose of this arrangement is to decrease the height'or extent of the 1 segment. Thus, it will be understood that if the securing shank for the screw were not off-set and lower than the ofi-set upwardly bent arms 16 of the terminal hanger, the screws for these hangers would necessarily be much higher than they are and that it would be necessary to make the segment higher or of a greater length than it is.

By providing hanger arms fora plurality of type bars on each hanger, it is necessary to use only about half as many fastening screws as pairs of hanger arms, and

consequehtly'larger screws'may be used and the parts be more securely held in place; yet ample space is provided for the screws and without the necessity of staggering them or inserting the screws from opposite sides of the segment. By the arrangement shown, the hangers may all be secured to the segment on the same side thereof and ready access to theholding screws 25 is afiorded from the front of the machine. It should be understood, however, that from certain aspects of my invention it is immaterial whether difierent sets of superposed staggered hanger arms are connected to the same shank or to different shanks.

Various changes may be made without departing from the spirit of my invention, and certain features thereof may be employed without the others.
